Earlier this week I posted about my rough running 77 Midget. The
consensus seemed to be start with the electrical system. This is what I
found.
1. The plugs were fine.
2. The gap on the points was < .015 and they seemed pitted. At least
they were not shinny and new. I replace and re-gapped the points.
3. The dizzy cap was shot. The carbon post on a spring that goes to
the center of the rotor was completely burnt away. The rotor also had
a big burn on the center where the post used to connect. I replace
both the cap and rotor.
4. I could not find any carbon traces anywhere until I started to
remove the spark plug wires. The number 1 wire had carbon traces only
were the wire went into the cap. I am using an older cap with the
post that screw into the wires. Since the wires were a bit long I
trimmed them all back and reused them. The number 1 wire I replace.
All of these parts were replace about 1K ago. It seemed a bit
fast to pit the points. The wire I am not sure why I had carbon
traces. The real question is why did the center post in the dizzy
just get burnt away in such a short period of time? Any ideas.
Anyway when I got done the car ran fine so I have fix my problems for
until the next 1K miles.
